solve for b ab+3c=2x, I got b=2x-3c/a

you need brackets

b = (2x-3c)/a

the way you have it , only 3c would be divided by a

To solve for b in the equation ab + 3c = 2x, you can follow these steps:

Step 1: Start with the equation ab + 3c = 2x.

Step 2: To isolate b, subtract 3c from both sides of the equation:
ab = 2x - 3c.

Step 3: Divide both sides of the equation by a:
b = (2x - 3c) / a.

Therefore, the solution for b is b = (2x - 3c) / a.

To solve for "b" in the equation "ab + 3c = 2x", you correctly isolate "b" on one side of the equation. Here's how you can do it step by step:

Step 1: Start with the equation: "ab + 3c = 2x".

Step 2: Move the term "3c" to the other side of the equation by subtracting it from both sides:
"ab = 2x - 3c".

Step 3: To solve for "b", divide both sides of the equation by "a":
"b = (2x - 3c) / a".

So, the solution for "b" is:
b = (2x - 3c) / a.

You can now substitute the values of "x", "c", and "a" into the equation to find the specific value of "b" based on the given values.
